If I may add,
Side effects for anti-Malaria tablets can result in serious mental problems.
One of my work pals went completely bonkers from anti-malarial tablets, had to be locked up for a couple of weeks, while locked up stopped taking the meds, then caught malaria while in the mental institution.
You also need to start taking the meds 2 weeks before travelling, so absolutely no use as a backup to keep in your bag.
